Hayom Yom: Menachem Av 4

No matter how much effort is exerted, no-one can earn one cent more than G-d has ordained that he - this particular person - shall earn. One must do what is necessary, but one must remember that all his work is but an adjunct. The main thing is G-d's blessing, and that blessing is earned by being observant of G-d's commands: Davening with a minyan, observing Shabbat b'hidur (beyond the minimum, with "beauty"), meticulous observance of kashrut, having children instructed by sincerely religious teachers.1
